Dude !!
I want 4 of those hinges!!
Just tell me where to throw my money ..... LOL
Seriously though, if you made up plans for those, could I get a copy of them?
For the past 18 months I have been struggling with the hinge problem for my bed concept, and the double action never occured to me, I kept fixating on the Porterbuilt style.
Something like this will work 100% better for my intended application.
If not on the plans, dont worry....I already stole the photo
